Title:
Universally Composable Contributory Group Key Exchange
Authors: M. Choudary Gorantla, Colin Boyd, Juan Manuel Gonzàlez Nieto
Abstract:We treat the security of group key exchange (GKE) in the universal composability (UC) framework. Analyzing GKE protocols in the UC framework naturally addresses attacks by malicious insiders. We define an ideal functionality for GKE that captures contributiveness in addition to other desired security goals. We show that an efficient two-round protocol securely realizes the proposed functionality in the random oracle model. As a result, we obtain the most efficient UC-secure contributory GKE protocol known.
